Answer:
BC = 24
Step-by-step explanation:
FD = 36, FE = 15 and CD = 18
By secant theorem.
DE • DF = CD • DB
(36 - 15) • 36 = 18 • DB
DB = 42
BC = DB - CD
BC = 42 - 18
BC = 24

The area of the figure is 26 square units. There is 6 of a 2 which adds up 12 and there is one 8 and adding it with 12 would be 20. The last number was a 6 so you add 20 with 6 which adds up of 26 square units. So the area Of the firgure is 26 square units.
Angle 4 + angle 1 must equal 180.
angle 4 = 65
180 - 65 = 115 degrees
Answer: 50% or 1/2
Step-by-step explanation:
To find the probability of a single outcome, divide the event by the total outcomes.
There are four blue spaces, which means each blue space is an event. It can land on any of the four spaces and still fulfill "spinner stopping on blue".
There are 8 total outcomes, including the blue spaces. 4 + 3 + 1 = 8.
Divide, 4/8 = 1/2. There is a 50% theoretical probability that the spinner will stop on a blue space.
